Suppose two line segments intersect. The two endpoints for the first line segment are (x1, y1) and (x2, y2) and for the second line segment are (x3, y3) and (x4, y4). Write a program that prompts the user to enter these four endpoints and displays the intersecting point. As discussed in Programming Exercise 3.25, the intersecting point can be found by solving a linear equation. Use the LinearEquation class in Programming Exercise 9.11 to solve this equation.

- Write a program that displays two chessboards, as shown in Figure 6.13. Your program should define at least the following function:# Draw one chessboard whose upper-left corner is at# (startx, starty) and bottom-right corner is at (endx, endy)def drawChessboard(startx, endx, starty, endy):The equation of a line in standard form is ax + by = c , wherein both aand b cannot be zero, and a, b, and c are real numbers. If b≠0, then –a/b is the slope of the line. If a = 0, then it is a horizontal line, and if b = 0, then it is a vertical line. The slope of a vertical line is undefined. Two lines are parallel if they have the same slope or both are vertical lines. Two lines are perpendicular if either one of the lines is horizontal and the other is vertical or the product of their slopes is –1. Design the class lineType to store a line. To store a line, you need to store the values of a (coefficient of x), b (coefficient of y), and c. Your class must contain the following operations: If a line is nonvertical, then determine its slope. Determine if two lines are equal. (Two lines a₁x + b₁y = c₁ and a₂x + b₂y = c₂ are equal if either a₁ = a₂, b₁ = b₂, and c₁ = c₂, or a₁ = ka₂, b₁ = kb₂ and c₁ = kc₂, and for some real number k.) Determine if two lines are parallel.

- Write a c++ program to assign passengers seats in an airplane. Assume a small airplane with seat numbering as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D 6 A B C D 7 A B C D The program should display the seat pattern, with an 'X' marking the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like this: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D 6 A B C D 7 A B C D After displaying the seats available, the program prompts for the seat desired, the user types in a seat, and then the display of available seats is updated. This continues until all seats are filled or until the user signals that the program should end. If the user types in a seat that is already assigned, the program should say that that seat is occupied and ask…using a C++ program code the problem, The game of "23" is a two-player game that begins with a pile of 23 toothpicks. Players take turns, withdrawing either 1, 2 or 3 toothpicks at a time. The player to withdraw the last toothpick loses the game. Write a human vs. computer program that plays "23". The human should always move first. When it is the computer's turn it should play according to the following rules: If there are more than 7 toothpicks left, then the computer should withdraw a random number of toothpicks (from 1 to 3). Use the rand() function, as demonstrated in class to produce this number.. If there are 2, 3 or 4 toothpicks left, then the computer should withdraw enough toothpicks to leave 1. If there is 1 toothpick left, then the computer has to take it and loses. When the human player enters the number of toothpicks to withdraw, the program should perform input validation. Make sure that the entered number is between 1 and 3 (inclusive) and that the player is…Airline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right. Geri bildirim gönder
- Write a program that reads from the user a character ('q' or 'c'). If the character is 'c', the program reads from the user the radius rof a circle and prints its area. • If the user enters 'q', the program asks the user to enter the length and width of a quadrilateral. We assume the quadrilateral is either a square or rectangle. You should print if the quadrilateral is square or rectangle. • Otherwise, it prints "Wrong character" PS: Use the following formulas: area of circle=3.14*r Sample Run1: Enter a character (q or c): q Enter the Length and Width: 80 150 |It is a rectangle Sample Run2: Enter a character (q or c): q Enter the Length and Width: 80 80 It is a square Sample Run3: Enter a character (q or c): c Enter the radius: 2 The area of the circle is 12.56 Sample Run4: Enter a character (q or c): d Wrong characterA regular polygon is an n-sided polygon inwhich all sides are of the same length and all angles have the same degree (i.e., thepolygon is both equilateral and equiangular).

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.
